Bitcoin core development language

1. Open source software, see: https://github.com/bitcoin/bitcoin/

2. According to your description, the reasons for voltage instability are as follows:
1. The outdoor power supply line is long, or the external wire section is small, resulting in large line loss. Once the home equipment with large power consumption is turned on (such as inction cooker, refrigerator, air conditioner, etc.), the line voltage drop is large, and the voltage is unstable. It is recommended to call the 24-hour power supply service hotline 95598, and the staff will follow up for you
2. The indoor wiring is unreasonable, the cross section of the main wire is too small, and when the equipment with large power consumption starts, the voltage drop is large, resulting in the instability of the same circuit voltage. It is suggested that for the equipment with large power consumption, separate circuit and separate wiring should be adopted
I hope our answers can help you.

3. Method / step
1 close the bitcoin client and find the file wallet.dat
WinXP start menu, select "run" and input the following contents: Explorer% appdata% bitcoin
Windows Vista or windows 7, directly input wallet.dat in the "search programs and files" box of the start menu to search
2 right click on the file and select "add to compressed file...", then the following dialog box will appear:
3 set a file name, Check "delete source file after compression"
then click the "advanced" tab:
4 click "set password..." and enter the same password twice in the pop-up dialog box
click "OK" and then click "OK" again to complete the encryption
5 you will see that the original wallet.dat file in the wallet folder is gone, but there is an additional. Rar file
6 encryption is successful
restore wallet
1 you just need to follow the steps of "back up wallet" (described in the previous experience) to open the wallet folder of bitcoin official client
2 the backup wallet.dat file to this folder, and then overlay the original file
precautions
if you use winrar to encrypt the backup, you need to enter the correct password first to restore the wallet.dat.

4. The development language is C + +, and the client interface is QT. It involves P2P, network programming, QT and so on.

5. Bitcoin is proced by mining. Mining is the process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary
network nodes are miners all over the world mining
only full node clients like bitcoin core need longer synchronization time. Technically, synchronization is a process of downloading and verifying all previous bitcoin transactions on the network. Some bitcoin clients need to know all previous transactions to calculate the available balance of your bitcoin wallet and complete new transactions. This step consumes a lot of resources and needs enough bandwidth and space to store the whole block chain. In order to maintain the security of bitcoin, enough users need to use the full node client, because they play the role of confirmation and relay transactions.

Wangxi village in the last lesson is Xiajiang village of Qian Lake in Hangzhou, Zhejiang Province

besides being deeply moved by teacher Fan Wei's acting skills, Wangxi village is the one who has great interest in this story. Shot from Xiajiang village in Chun'an County. When driving around Qian Lake, Xiajiang village is a good choice if you want to find a place to eat and rest

There is also the end of the story, the primary school that evolved from a black and white painting into reality. The glittering appearance is just like a candy castle, which amazes all of you

What's more amazing is that this primary school is not a special effect, nor a scenery, but a real existence. It is Fuwen Township Central Primary School in Chun'an County, Hangzhou city. It took the government five years and 10 million yuan to build this dream primary school
